MOTOR-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 664,853, dated January1, 1901.

Application filed December 23, 1897. serial No. 663.170. \llo model.)

To all whom it ntcty concern:

Be it known that I, RUDOLF HAGEN, a subjeot of the.King of Prussia,German Emperor, and a resident of Gologne-on-the-Rhine, in the Provinceof the Rhine, German Empire, have invented new and useful Improvementsin Motor-Vehicles, of which the following is a specification.

My invention relates to improvements in motor-vehicles, and comprisesspecially the means for changing the speed of the vehicle withoutchanging the speed of the motor. I attain this object by means of thelever mechanism illustrated in the accompanying drawings, in which-Figure 1 is a view of the whole mechanism. Fig. 2 is a section of adetail of it on line X Y, Fig. 1.

The drawings represent the system of levers employed for changing thespeed of the vehicle in connection with a single-cylinder engine. Thefly-wheel a. is not arranged on the main shaft is, but a special shaft Zis provided which runs with greater velocity than the main shaft inorder to be able to make the fly-wheel as small and as easy as possi bleand to effect an easier possibility of starting the engine by turningthe fly-wheel. The movement of the main shaft'k is transferred by meansof a crank or an eccentric and of the connecting-rod m to thevertically-oscillating slot-ted arm 0. In the slot of this slotted arm 0slides a block g, that is pivotally connected with the slide-block n,Fig. 2. The latter slides in the slotted arm of a doublearmed lever e,the ends of which are linked to the rods h i, so that the lever e,pivoted at f, oscillates together with the arm 0 and that the rods 77,2' alternately move the driving-levers 0 p. The latter are looselyarranged on the axle of the vehicle and act in common with the clutchmechanism in the well-known manner only in one direction. It is clearthat by means of the described parts a continued turning of the hindwheels (the drivingwheels of the motor -vehicle) takes place. The twoconnected slide-blocks g and n are by means of the connecting-rods rfixed to the common pivot-boltof the two blocks fixed to the arm 5,pivoted at t. This arm 8 is furnished with a handle and may be held indifferent positions by means of the ratchet u and the pawl 12.

By dislocating the slide-block g Within the slotted arm 0 the efiectivelength of the latter is diminished or increased. As the slideblock g isconnected with the slide-block n the latter is removed, together withblock g, and the effective length of the upper arm of the lever e iscorrespondingly changed. The displacement of the slide-blocks isoffected. by means of the hand-lever 8 above mentioned. If the blocksare pushed up, the effective length of the lever c is diminished, whilethat of thelever e is increased, Whereby a double diminution of thestroke of the driving-leverand a decrease of the velocity of the vehicleare attained. By pushing the slide-blocks down the speed of the vehicleis increased.

The stroke of the lever 9 may be increased to the maximum or diminishedto zer0?l. 6., to the complete stoppage of the vehicle although themotor continues its rotation. For the latter purpose the slot of thelever c is extended beyond the pivot w, so as to permit it to bring theslide-block in a position in which its pivot is coincident with thepivot to of the lever c. In this position of the slideblock 'ntheoscillation of the lever o is no more transmitted to the lever e. Theadvantages of this lever mechanism are most important formotor-vehicles, as the mechanism for changing the speed of the vehicleexclusively consists of levers pivotally attached to inflexible axlesmounted on the engine, and therefore the loss of power on account offriction is reduced to a minimum, and as bythe employment of adouble-armed lever, the movement of both arms of which is transferred tothe axle by stiff rods, so that always one end of the lever isin action,only one system of levers is necessary.

Whatl claim, and Wish to secure by Letters Patent of the United States,is

1. In motor-vehicles the combination of an oscillating slotted one-armedlever e inflexibly pivoted to the engine at w and operated from the mainshaft of the motor, with a double-armed lever e inflexibly pivoted tothe engine at f, the upper arm of this lever being provided with a slot,stifi connectingrods attached to the ends of both arms of thedouble-armed lever e and adapted to transmit the motion of the lever tothe driving-axle of the vehicle by means of a clutch mechanism, twoslide-blocks g and it connected one with the other by means of a commonpivotbolt and'fit for sliding in the slots of the levers c and erespectively and means for moving these connected slide-blocks g and nas and for the purpose set forth.

2. In motor-vehicles the combination of an oscillating slotted one-armedlever c inflexibly pivoted to the engine at w and operated from the mainshaft of the motor with a double-armed lever e infieXibly pivoted to theengine at f, the upper arm of this lever being provided with a slot,connecting-rods attached to the ends of both arms of the double-armedlever :e and adapted to transmit the motion of the lever to thedrivingaxle of the vehicle by means of a clutch mechanism, twoslide-blocks g and 01 con- 7 nected with a main shaft by means of gears7 as and for the purpose set forth.

In witness whereofI have hereunto set my hand in presence of twoWitnesses.
